Abstract: 1516427 Controlling light HAGIWARA DENKI K K 20 April 1976 [22 April 1975]  16008/76 Heading G2F In a modification of an electro-optic diffraction device comprising a parallelepipedal substrate of electro-optic material with a pair of plane parallel optical input and output faces, and an inter-digital electrode or a single electrode pair on a further face, with fingers extending parallel to the intended optical path, one or both of the other pairs of faces consist of mutually inclined planes, or comprise a non-planor (corrugated or curved) surface, to reduce acoustic resonances in the substrate particularly at operating frequencies where the acoustic wavelength and the inter-digital electrode spacing are comparable. In addition an acoustic absorbe such as solder, or epoxy or cyanoacrylate resin may be affixed to one of the non-optical faces, or the latter may be coupled to a medium with an acoustic impedance close to that of the substrate and provided with alternating means or an irregular boundary to prevent coherent reflection of the acoustic waves. The use of epoxy resin loaded with metal powder is referred to. In use the optical sea preferably undergoes total internal reflection at the centre of the face housing the electrode. In a variant form of device there is an optical guiding layer between the substrate and the electrode so that the substrate need not have optical input and output faces, and optical couplers are provided at either end of the layer.

Title: Process for treating wood for surface ornamentation
IPC: B44F9/02
Filed: 1932-09-10
Abstract: 411,496. Ornamenting wood. McCARTNEY, R., 30, Munro Road, Jordanhill, and BROWN, J., 23, Greenfield Road, Spring- boig, both in Glasgow. Sept. 10, 1932, Nos. 16398/32 and 3329/33. [Class 93.] In a process for treating wood for surface ornamentation, a sheet of the material is first softened by steam or otherwise, and, while soft,is pressed between heated complementary dies so as to configure or wave the grain or fibre throughout the thickness of the sheet, the heat of the dies setting the grain as configured or waved, and is finally planed or otherwise treated to form a smooth surface on either or both sides. The dies may simply bend the grain of the wood, or they may form characters or designs to simulate the grain of expensive woods. A number of sheets similarly shaped by dies may be secured together and then cut to show more or less of the component sheets. In an example, Figs. 10 and 11, wood is treated to resemble bird's-eye maple, the exposed protuberances representing the eyes. Also, such an assemblage of sheets may be cut at an angle. Further, a thick sheet of wood after shaping to provide relatively large projections and depressions may be cut into thin sheets each of which is then softened and subjected to the action of dies having projections of smaller area, each sheet being then planed to form smooth surfaces. To avoid causing damage to the wood by the dies, the softened wood may be subjected to end pressure, e.g., the wood w, Fig. 8, is bent prior to placing between end stops e, f, which hold it during the action of dies a, b alternatively, the stop f may be utilized as a ram to bend the wood. For the same purpose, also, the dies may be brought into operation in stages, first to avoid buckling of the wood and second to complete the shaping when the wood is in a state of compression.

Inside the casing is a sleeve 20 having a flange 20<1> between which and the cover plate 17 is a spring 22 which is strong enough to hold the cover plate against the nuts 19 in spite of the force exerted on the knife edges so that the cover plate can be set with its axis in coincidence with the axis of the casing and with the correct distance between the knife edges 11 and the ball 1 so that when the balls 1 and 2 are pressed together, the beam is horizontal. The forward part of the cover plate carries a bracket 23 supporting a pillar 24 on which pivots a weighted lever 25 connected by links 27 and knife edges to the beam 15 at the centre of gravity of the latter. The weight 26 exactly balances the dead weight of the beam. Channels 39 are provided through which a wire may be pushed to release the balls 1, 2, the pressure between which may be released by operating the lever 61 which presses against the flange 63 and also moves a rod 64 against an abutment 65 to ease the load on the lever. A microscope, adjustable in three directions at right angles by means of screws 32, 33, 34 is provided at the left hand for viewing the area of contact on the ball 1 after the carrier 4 has been turned through 180‹, light, tangentially to the ball, being admitted through a channel 38. The balls may be coated with silver sulphide for the test. A sliding rod 44 located half in the part 4 and half in the casing 18 is adapted to receive a film carrier 47 carrying at its lower edge a film on which is projected a shadow of the area of contact by X-rays projected through the channel 43 from a Rontgen ray apparatus located in the base of the hollow pillar 29. The rod 44 and film carrier 47 may be moved at right angles to the paper in order to make several exposures. To test friction three balls are used the carrier 4 being cut away to admit a ball between balls arranged as in Fig. 2, the third ball being supported by friction between the other two and carrying a light beam from the ends of which are hung scale pans in which weights are placed. The Hertz test mav be carried out by providing the plunger 6 with an extension so that the ball 2 may engage a quartz plate the Newton rings formed at the contact area being viewed through the microscope.

[Class 141] A swimming suit or like close-fitting garment for ladies' wear has the frontal portion of the upper part divided from the sides, and formed narrower than usual so as to extend only across the breast of the wearer, the side edges of this portion being convexly curved so that it is widened substantially at the point of maximum bust measurement, while the part of each side portion corresponding to this curved portion is either substantially straight or convexly curved so that when the edges are attached together, a certain fulness is produced in the region of the breasts. Preferably, the sides are provided by two separate inserts. In the form shown, applied to a bathing costume having a low-cut back, each insert 7 begins from the point where the usual shoulder straps 8 are attached to the garment and is formed in a convex curve 3x corresponding to the convexly curved part 3 of the frontal portion 1, and is shaped at its lower edge 4<x>, 5<x> so as to occupy a substantially semicircular cut-out, which extends down at 4 from the edge of the frontal portion 1, and bends upwards at 5 to meet the top edge 6 of the back of the garment. The free edges 9 of the inserts 7 are cut substantially straight but, in position on the wearer, appear to be continuous with the curved edge of the back, and are hemmed over, and may be threaded with elastic. The body portion of the garment is knitted, in the usual way, with ribs running longitudinally, while the inserts are kntted with ribs running parallel to their free edges 9. As applied to garments which are not low-cut at the back, the edges 9 of the inserts, instead of being free, are secured to corresponding edges of the back portion.
